我在将pandas导入iPython笔记本时遇到了一些问题。但是，当我将pandas导入python shell时，它可以工作。
让我们来看看我的代码：
from __future__ import division
import pandas as pd
import numpy as np
churn_df = pd.read_csv('churn_data.csv')
col_names = churn_df.columns.tolist()
print "Columns names:"
print col_names
to_show = col_names[:6] + col_names[-6:]
print "/nSample data:"
churn_df[to_show.head(6)]
我收到了这个错误：

所以，如果我只是尝试导入pandas：
from __future__ import division
import pandas as pd
import numpy as np
我收到了这个错误：
ImportError Traceback (most recent call last)
<ipython-input-2-f13a6d5d1db6> in <module>()

14
15 from datetime import datetime
ImportError: C extension: hashtable not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace' to build the C extensions first.
然而，当我检查python shell时，我看到了：
me-3:python me$ python
Python 2.7.10 (default, Sep 23 2015, 04:34:21)

Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas
>>> print pandas.__version__
0.17.1
我因为我做错了而感到茫然。我想这可能是因为我安装了多个版本的python，但我不太清楚这个问题是什么。

答案 0 :(得分：0)
在笔记本类型中：
In [1]: %ls matplotlib.py
如果您看到列出的文件matplotlib.py，请删除或重命名该文件（使用命令行或文件浏览器等工具）并再次尝试导入。
